Essential's Audio Adapter HD has finally been announced. The company has been talking about the existence of this new external headphone jack/DAC since June, and this month's security update indicated we'd see it soon. But there are a few twists: It's $150, and a limited edition.

Andy Rubin originally promised new wireless accessories "every few months," but for whatever reason, it seems the company wasn't able to stick to that schedule. It's possible a lawsuit surrounding the modular accessory communication tech could have had something to do with the delay.

Audio Adapter HD is here. A limited-edition DAC for Essential Phone, delivering one of the best mobile audio experiences available today.

We're not entirely convinced of the merits behind such sky-high bit-depth and sampling rates, ourselves, but they're an option if you're interested. The Audio Adapter HD's built-in amp is also able to better power high-impedance headphones via the 3.5mm output, and it's IP55 rated. Full specs are available here.

Essential's omission of the headphone jack was a point of contention for many, including us. While you could use a dongle, now there's another higher-end (and more expensive) option. Just remember, Essential says this is a limited edition.

Essential has already burned through its inventory, selling out all the Audio Adapter HDs it had. The company expects to get more in next week, though. It may be a limited edition, but your chance isn't gone (yet).
